Oh, Look! Olivia Munn's Hair "Grew." Which Length Do You Like Best?

The hair Olivia Munn was flaunting at the premiere of HBO's The Newsroom is gorgeous, but it's not the same hair she had three days ago. Come view the evidence.

Exhibit A: On June 18th she showed up at the Critic's Choice Awards with her signature bob. She looked great–I'm digging her imperfect part and tousled ends.

Exhibit B: This is how Olivia looked last night. Suddenly, her hair hangs past her shoulders! This switcheroo has to be the result of extensions or a weave (Malin Akerman pulled the same stunt recently). Either way, I think her hairstylist did a bang-up job. Her longer hair looks pretty and very believable.

But you know what's coming next: Yep, I'm going to make you choose. Which length suits her best? Which one would you go for?
